To all whom it may concern;

Be it known that I, LEoN SER-POLLET, of Paris, Republic of France, have invented a new and useful Improvement in Liquid-Fuel Burners, which are fully set forth in the following specification, and for which I have ob tained a patent in France, No. 263,585, dated January 30, 1897.

In a liquid-fuel burner according to this invention the vapor of petroleum or other liquid hydrocarbon is injected under pressure into a Bunsen passage and is burned in contact with air, which is drawn in by the jet and is heated by contact with the body of the burner and with the flame.

The invention will be best understood by reference to the accompanying drawings, wherein- Figure 1 shows a central vertical section of a burner constructed in accordance with this invention. Fig. 2 is a longitudinal vertical section on the line Y Y of Fig. l, and Fig. 3 is a front elevation thereof.

In the drawings I have shown a burner embodying my invention, in which horizontal Bunsen jets are placed outside the furnace under the eye and hand of the stoker, and thus removed from. the action of the heat generated by the ignited jets, which are chiefly consumed in the furnace under the apparatus to be heated.

A represents the firechamber of a furnace of suitable construction, having an opening Z) through the wall thereof, through which the flame of the burner enters the furnace.

A, is the body of the burner, suspended by suitable ears from the front of the furnace over the opening I), having a series of horizontal transverse Bunsen passages G',extending through the upper part thereof from the front to the rear, and a series of longitudinal connecting-passages D, D, D, D,, extending at right angles to passages G, the upper passage D, connecting through small transverse passages H, with forked tubes E, E, E,, carrying injector-nozzles F,.

The petroleum, coming from a suitable reservoir (not shown) under pressure to the bot tom of the body A, of the burner, preferably by the pipe (3,, and entering at the center of the lower passage 1),, iiows in the direction indicated by the arrows and becomes gradually heated and vaporized in the passages D, D", by contact with the heated material of which the burner is composed. From the upper passage D, the hot combustible vapors are distributed by the passages l-I, into the simple or forked tubes E, E, E",, each provided with a nozzle F, fora B unsen jet. Each nozzle thus projects under pressure along the axis of each of the Bunsen passages G a jet of hot vapor, which is caused by contact with the surrounding air drawn in by it to form a continuous horizontal jet of flame, which heats the walls, as also the mass of the rear portion of the body of the burner and, becoming in its turn heated by reaction, enters the furnace, where it spreads and heats the parts to be heated.

The burner is provided with a discharge tube H and cleaning-plugs I, I", 1",.

The body of the burner, suspended by means of lugs against the surface (of refractory material) of the furnace, from the heat of which it is removed, may be covered or inclosed by means of a thin sheet of metal S, which has holes 5 3 made through it to allow of an abundant supply of air. A passage L, allows to be drawn into the furnace a supplementary quantity of air, which may be regulated so as to effect a complete combustion of the combustible petroleum-vapors that would otherwise escape, being burned either in the jet or flame formed at the center of the Bunsen passage or at the outlet of the said passage.

Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed,

I declare that what I claim is- 1. In an apparatus for the combustion of petroleum or other heavy oil, comprising a burner-body of refractory material arranged adjacent to the fire chamber, a series of burner-orifices in said body opening into said chamber, a series of nozzles or burners discharging into and through said orifices, and a series of channels-inclosed in said body and communicating one with another and the last with said nozzles, so that the oil is gradually heated as it approaches the burners and finally converted into high-tension vapor,substantially as described.

2. An apparatus for generating and consuming the vapors of petroleum or other heavy mineral oil arranged contiguously to the fire-chamber, said apparatus consisting of a series of burners axially and centrally located at the outer end of corresponding open orifices horizontally traversing the body of said apparatus, and a series of closed but intercommunicating channels also Within the body of said apparatus for the passage of the oil before reaching the burner, said channels bein g arranged in series underneath the burnerorifice so that the oil may become gradually heated and finally converted into hightension vapor; and lastly of a channel also in the
